Hmm. Yeah, I'm seeing that in the docs too. So perhaps the __LPM macros are 
not in error, but perhaps the __ELPM macros are? (for listing Z reg in 
clobber list) Interestingly, I've never had any problems with compiling 
with the __ELPM macros and I haven't heard of any similar problems...

Anybody else have thoughts on this?
